  • Late MIS 3 stabilization of dunes in the eastern Central Great Plains, USA
    • Abstract: Publication date: February 2019Source: Aeolian Research, Volume 36Author(s): William C. Johnson, Alan F. Halfen, Joel Q.G. Spencer, Paul R. Hanson, Joseph A. Mason, Aaron R. Young Extensive luminescence and 14C dating of aeolian sand dunes and sheets in the Central Great Plains (CGP) have been biased toward the western part of the region, targeted relatively large dune fields, and produced primarily Holocene (Marine Isotope Stage (MIS) 1) and latest Pleistocene (MIS 2) ages. This research luminescence dated a small discontinuous dune field perched on the high terrace of the Kansas River valley, situated on the eastern side of the CGP. These dunes have been stable since at least 30–28 ka, indicating that they are among the oldest recognizable dunes preserved in the CGP, as well as the entire North American Great Plains. The inferred stabilization of these dunes was coeval with pedogenesis and low sediment accumulation rates in upland loess, playa lunettes, and alluvial sequences in the CGP, in a time period with maximum summer insolation and relatively warm conditions. Source of the sand is presumed to have been fluvial sediments from the adjacent Kansas River, now preserved as the Buck Creek Terrace. Sand-mobilizing winds were southerly to southwesterly given that the dunes mantle only the high-terrace remnants on the north side of the valley. Long-term dune stability after MIS 3 appears to indicate that latest-Pleistocene and Holocene megadroughts were not sufficiently severe and eastward penetrating to reactivate these eastern CGP dunes.
       
  • The utility of an omni-directional photoelectronic sensor device to
           measure meso-scale variability in aeolian sediment transport activity
    • Abstract: Publication date: February 2019Source: Aeolian Research, Volume 36Author(s): Phillip Schmutz, Tynon Briggs, Peter Tereszkiewicz Electronic sensors (i.e., acoustic, piezoelectric, and photoelectric) have been utilized extensively and effectively in recent years for measuring aeolian transport intensity. The bulk of these studies, however, position the devices in stationary, fixed orientation during field experiments. These practices work fine for shorter, micro-scale field studies; yet, during longer experiments lasting months or even years, a fixed directional orientation is unrealistic due to shifts in wind direction. This issue has ultimately limited the use of electronic sensors for meso-scale aeolian research. In light of this constraint, this paper presents a device to measure aeolian transport activity across a 360-degree azimuthal range. The Rotating Wenglor Device (RWD) was deployed on Santa Rosa Island, Florida for a three-month field study. The data reveal that the prevailing transport activity did not align with the dominant wind direction. The implications of this finding can be further elucidated when analyzing our data using the Fryberger drift potential model. Our findings indicate that the traditional Fryberger method, constructed using our wind data, produced a resultant transport drift towards the northwest; however, the RWD illustrated a resultant transport direction towards the northeast and at a rate three times slower. These finding highlights a major benefit of the RWD as it would produce a more accurate measure of meso-scale transport activity and therefore dune development than models derived strictly from meteorological station data, such as the Fryberger method. An additional advantage of the RWD is that the device operates unattended for extended periods, yet can provide high-resolution data regarding micro-scale transport dynamics.
       
  • Examining links between dust deposition and phytoplankton response using
           ice cores
    • Abstract: Publication date: February 2019Source: Aeolian Research, Volume 36Author(s): James Hooper, Paul Mayewski, Samuel Marx, Stephanie Henson, Mariusz Potocki, Sharon Sneed, Mike Handley, Santiago Gassó, Matthew Fischer, Krystyna M. Saunders Dust is a major source of nutrients to remote ocean environments, influencing primary productivity (PP). Enhanced oceanic PP causes drawdown of atmospheric CO2 and is considered likely to be a driver of climate variability on glacial-interglacial timeframes. However, the scale of this relationship and its operation over shorter timescales remains uncertain, while it is unclear whether dust fertilisation, or other mechanisms, e.g. nutrient upwelling, are the primary driver of PP in high-nutrient low-chlorophyll (HNLC) ocean regions. In this study, we demonstrate, using dust derived Fe and Methanesulfonic acid (a measure of ocean PP) deposition in ice cores from the South Atlantic (South Georgia Island) and North Pacific (Yukon), that PP is significantly correlated with Dust-Fe on both an event and annual scale. However, measuring the relationship between (dust) Fe fertilization and PP in high resolution ice cores is subject to a number of highly complex factors, which are discussed and together used to recommend future research directions. In conclusion, our research suggests that changes in aeolian Fe flux, due to climate change and human activity in dust source regions, could have significant implications for HNLC ocean PP and, therefore potentially, carbon sequestration.
       
  • Effect of wind speed on aggregate size distribution of windblown sediment
    • Abstract: Publication date: February 2019Source: Aeolian Research, Volume 36Author(s): Rende Wang, Qing Li, Na Zhou, Chunping Chang, Zhongling Guo, Jifeng Li Wind speed is critical in wind erosion and dust emission processes; however, previous studies, especially field measurements, have been unable to verify the effect of wind speed on particle size distribution of windblown sediment. The aim of this study was to elucidate changes in the aggregate size distribution of windblown sediment in relation to friction wind velocity based on field observations conducted during 2012–2018 in Bashang District (North China). The results showed that for loamy, sandy, and sandy loam soils, the geometric mean diameter of sediment increased exponentially with increasing friction wind velocity. The mass percentages of particles with diameters of
       
  • A study on the fragmentation of saltating particles along the fetch
           distance during wind erosion
    • Abstract: Publication date: December 2018Source: Aeolian Research, Volume 35Author(s): Fernando Avecilla, Juan E. Panebianco, Daniel E. Buschiazzo PM10 emission largely depends on the characteristics of the saltation process, which involves the movement of aggregate and isolated particles. Studies analyzing the relationship between the fragmentation of saltating aggregates and the dust emission along the fetch distance are very scarce. The objective of the present study was to analyze, on a loamy texture soil, the changes in the size distribution of the eroded sediment along the fetch distance under field conditions. Changes in the particle size distribution of the transported material were measured at four different heights above the soil surface every 25 m on a 200 m plot, during three strong wind erosion events. Statistically significant differences were found both for particle size distribution and aggregation when comparing the eroded sediment at the windward and leeward sides of the experimental plot. A greater proportion of coarser particles was found as the distance traveled by the eroded sediment increased. From the change in average particle size distribution at the beginning and at the end of the 200 m experimental plot, it was estimated that around 12% of the particles smaller than 62.5 μm were lost by vertical transport (dust plume) producing an average concentration of 48 µg m−3 at 2 m height and 200 m fetch. Under the conditions of this experiment, a soil aggregate transported by saltation was fragmented at a rate of 38% every 100 m traveled (R2 = 0.88; p 
       
  • Prediction of aerosol optical depth in West Asia using deterministic
           models and machine learning algorithms
    • Abstract: Publication date: December 2018Source: Aeolian Research, Volume 35Author(s): Seyed Omid Nabavi, Leopold Haimberger, Reyhaneh Abbasi, Cyrus Samimi Because of the lack of ground-based observations in large parts of West Asia, Aerosol Optical Depth (AOD) is mainly monitored by using remote sensing techniques. AOD can also be predicted by short term forecasts with commonly called Deterministic weather prediction models (DMs). The skill of DMs in reproducing remotely sensed observations when averaged over monthly time scales over West Asia is rather limited due to significant uncertainties in inputs and complexity of dust, which is the dominant type of aerosols in the region.Machine Learning Algorithms (MLAs), which require much less computational expenses than DMs, can be used. Using Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue (DB) AOD as the representative of response variable, MLAs, especially Multivariate Adaptive Regression Splines (MARS) and Support Vector Machines (SVM), outperformed DMs on monthly time scale. MLAs have yielded lower prediction error (RMSE) and higher correlation with observations than DMs. In addition, findings disclosed that DMs, especially MACC, have failed to simulate observed AOD values over western Iran where the Zagros Mountains prevent advection of fine dust particles to the east of the study area. Prediction errors of MLAs and DMs along with major DB AOD peaks, over Iraq, can be traced back to the rough resolution of variable datasets, omission of some unknown influential predictors representing the life cycle of dust and/or other aerosols, and scarcity of extreme cases. It also remains to be tested in how far the results presented can be generalized to other regions and time scales.
       
  • Distribution patterns and morphological classification of climbing dunes
           in the Qinghai-Tibet Plateau
    • Abstract: Publication date: December 2018Source: Aeolian Research, Volume 35Author(s): Miao Dong, Ping Yan, Baoli Liu, Wei Wu, Xiaonan Meng, Xinran Ji, Yong Wang, Yijiao Wang In this study, the climbing dunes in the Qinghai-Tibet Plateau were digitalized through Google Earth images and field examinations in order to facilitate the investigation of their distribution patterns and to allow their classification. The results of this study showed that the total area covered by climbing dunes in the Qinghai-Tibet Plateau is about 30,075 km2, which represents 7.5% of the total area of aeolian landforms in the plateau, and 1.15% of the entire plateau area. The climbing dunes of the Qinghai-Tibet Plateau were densely distributed in the Qaidam Basin, Gonghe Basin, Kumukuri Basin, foothills of the Qilian Mountains, foothills of the Altun Mountains, and the Southern Tibet Valley. Sporadic distributions were also observed in the river and lake basins of the Hengduan Mountains, Qiangtang Plateau, and the Ali Plateau. The average climbing height of the climbing dunes in the Plateau was 191 m, with the maximum and minimum climbing height being 1416 m and 3 m, respectively. Based on morphogenetic principles, we have established a classification diagram for climbing dunes of the Qinghai-Tibet Plateau; on going from the base of a slope to the crest, the morphologies of the dunes increased in complexity and the age of their formation grows earlier. The development of climbing dunes is related to interactions between wind regime, sand materials, dry climate, undulating terrain and accommodation space. The research results of the climbing dunes on the Qinghai-Tibet Plateau could contribute to the understanding of aeolian landforms.
       
  • Detection of aeolian transport in coastal images
    • Abstract: Publication date: December 2018Source: Aeolian Research, Volume 35Author(s): Isaac A. Williams, Kathelijne. M. Wijnberg, Suzanne. J.M.H. Hulscher Optical remote sensing provides a low cost method of documenting surface conditions over extended periods of time. Its utility in resolving large scale aeolian transport events is examined in this paper. To this end, over 1800 images taken over a three month period by a stationary camera in a coastal setting are classified as containing/ not containing aeolian transport using both a manual and automated approach. In both cases transport is inferred by the identification of aeolian streamers within a given image. With regards to the manual approach, images were visually examined by three users. There was good agreement between the different users with 77.8% of transport identifications being unanimous. Comparison of the user results with measured transport highlights that observations of transport in images coincide with increased particle counts. The particle counts indicate that transport is dominated by a series of discernible transport events. Transport is observed in images throughout the duration of these events. Manually processing the images is a laborious process. A method is presented which allows for the automated detection of images containing transport. The method utilises 2D-DFTs to exploit the linear appearance of streamers in images. Relative to the manual classifications which serve as ground truth, the method performs well in identifying images containing transport with values of precision, recall and F1 score ⩾0.85.
       
  • Wind speed characteristics and blown sand flux over a gravel surface in a
           compact wind tunnel
    • Abstract: Publication date: December 2018Source: Aeolian Research, Volume 35Author(s): Jiaqi Liu, Reiji Kimura We investigated the influence of gravel coverage on roughness length and blown sand flux in a compact wind tunnel equipped with a turbulence generator and a piezoelectric blown sand meter. At gravel coverages from 5% to 15%, roughness length increased with increasing coverage. However, at coverages of 20% or greater, roughness length reverted to its value at 0% coverage. At the lowest wind speed of 6 m s−1, blown sand was fully trapped at gravel coverages of 15% or greater; however, coverage affected sand flux little at wind speeds of 8 and 9 m s−1 and had no effect at a wind speed of 10 m s−1. The increase in roughness length with gravel coverages from 5% to 15% corresponded to a decreased blown sand flux at heights less than 8 cm. However, at 8-cm height, a greatly decreased roughness length at higher gravel coverages (20%–30%) corresponded to a notable increase in blown sand flux, a change we attribute to aerodynamic smoothing.
       
  • A multi-proxy late Holocene climate record from aeolian deposits of the
           Horqin sandy land, northeast China and its societal implications
    • Abstract: Publication date: December 2018Source: Aeolian Research, Volume 35Author(s): Shuang Zhao, Dunsheng Xia, Heling Jin, Jia Jia, Bing Liu Late Holocene climate change is an important issue in global change research, because of its close relationship with human societal development. The Horqin sandy land is an important area for early dryland agriculture development. However, the role that climatic factors, especially temperature and precipitation, played in regional agriculture development is still unclear. This paper presents a high-resolution multi-proxy palaeomoisture record spanning 4300–1000 cal. yr BP derived from sequential aeolian sediments of the Liuhutun section on the northeastern frontier of the Horqin sandy land, northeast China. The 2.96 m section, with a chronology based on seven radiocarbon dates, was analyzed for sediment grain-size, CaCO3 content, organic matter content and environmental magnetic parameters. The results indicate that 4300–3800 cal. yr BP was a humid period with a drying trend; that 3800–1700 cal. yr BP was generally dry; and that 1700–1000 cal. yr BP was sub-humid. It is clear that the regional climate was responsive to East Asian monsoonal circulation driven by variations in Northern Hemisphere summer insolation. We further investigate the relationship between climate change and regional agriculture development by comparing moisture records with regional temperature and subsistence strategy changes inferred from previous studies. The results suggest that high temperature and moderate precipitation may have facilitated agricultural development during the Lower Xiajiadian period (ca. 4000–3400 yr BP). Owing to the drought-tolerant and thermophilic phenological properties of millets, which are major crops of northeast China, temperature may have played a more important role in regional agriculture than precipitation.
       
  • Modeling the bistability of barchan and parabolic dunes
    • Abstract: Publication date: December 2018Source: Aeolian Research, Volume 35Author(s): Gershon Hanoch, Hezi Yizhaq, Yosef Ashkenazy Extensive areas in arid and semi-arid regions of the world are covered by sand dunes. Sand dunes can be active, semi-active, or stable, depending on, among other factors, their vegetation and biogenic crust covers. Vegetation growth on barchan dunes can induce a transformation to parabolic dunes with long trailing arms pointed upwind. Here we propose a vegetation dynamical model, coupled to a previously suggested 3D continuous dune morphology model (Durán and Herrmann, 2006). The modeled vegetation reduces sand flux, but it is also suppressed by erosion and by sand deposition. The coupling between the model for bare dunes and the model for vegetation growth is performed by reducing the shear stress due to the presence of vegetation. We use the suggested model to study the effect of vegetation on dune formation, concentrating on the previously simulated barchan-parabolic dune transition. Under the action of sufficiently strong unidirectional winds and a low vegetation growth rate, the model results in a barchan dune. When the vegetation growth rate is increased, the barchan dune turns into a stable parabolic dune. When, however, the growth rate is again decreased, the dune becomes an active barchan dune, only with a much lower growth rate, indicating the existence of bistability and hysteresis behavior of barchan and parabolic dunes under similar climatic (vegetation growth rate or precipitation) conditions.
       
  • New evidence for the provenance and formation of loess deposits in the Ili
           River Basin, Arid Central Asia
    • Abstract: Publication date: December 2018Source: Aeolian Research, Volume 35Author(s): Yue Li, Yougui Song, Kathryn E. Fitzsimmons, Xiuling Chen, Qiansuo Wang, Huanyu Sun, Zhiping Zhang Loess deposits are thick and widespread along the piedmonts of Arid Central Asia (ACA), however the source (provenance) and processes of formation of these fine-grained aeolian deposits are poorly understood. Here we investigate the provenance and possible distribution mechanisms for loess along the slopes of the Ili River basin, located in northwest China and southeastern Kazakhstan, using a grain-size mixture model and an elemental geochemistry-based source fingerprinting technique. Our results indicate that the Ili loess experiences low rates of sedimentary recycling downstream within the basin piedmont, and are strongly dependent on local geomorphic context. Loess deposits are dominated by proximal sources, indicating short-distance aeolian transport from the Ili River alluvial plains and local proluvial fans. Local sourcing dominated regardless of location within the catchment, although the proportion of fluvial input increases proportionally with increasing distance downstream. Our results suggest that the Central Asian deserts did not act as significant interim storage reservoirs for the loess deposits in the Ili River basin, which contrasts with the popular model for piedmont loess formation across Central Asia. Most likely the relatively enclosed and highly variable basin topography precluded transport from the open desert steppe into the upper Ili River valley. Our study provides the first clear evidence for a genetic link between the Asian high mountains and the loess of the adjacent piedmonts, based on geochemical and grain-size data, with the caveat that the high degree of topographic variability along the Tianshan piedmont likely results in a strongly localized influence on loess formation and accumulation.
